What is a spotlight? What is the working principle of magnesium light?

Everyone must have heard of the spotlight, but what exactly is it? You may not understand. Then, let Bian Xiao let everyone know what a spotlight is.

Introduction of magnesium light:

The magnesium light is actually the light emitted by our camera when taking pictures, also called flash. I still remember that photographers in relatively backward times would give off a burst of light when taking pictures, which would be like the sound of explosion. That is, they use magnesium powder as a flash, so they borrow a flash to take pictures, because it becomes a magnesium light.

Nowadays, in this era of advanced technology, electronic flash has been used, and the effect can be said to be very remarkable. Now many photo studios and some photo studios have magnesium lights, especially the studio magnesium lights, which are necessary. The photos taken with the magnesium lamp are very obvious and good. In our technologically advanced society, Meguiar's lamp has been widely used by many photographers. Photographs taken with a camera like this look very clear and natural, which has a good effect both technically and in the use of flash. Its light is very uniform and the effect is very good.

For example, many stars go to the photo studio to take pictures. There is a simple reason. If you take pictures in the studio, because there is a spotlight, the effect will be good. That's why every star we see is so handsome and beautiful.

Nowadays, many people in this society like to spend a lot of money to take some artistic photos of their own style. Art photos are called art photos because they are used in the spotlight, so the photos taken are very beautiful and handsome.

The use principle of magnesium light:

Both magnesium and xenon can be used in photographic flash. Xenon flashlights can be used thousands of times, while ordinary magnesium lamps can only be used once.

Xenon uses physical properties: when the shutter button is pressed, a switch of the camera instantly starts the flash; At the same time, the high-voltage power stored in the flash capacitor is discharged in the xenon (Xe)-filled lamp tube during the flash, resulting in a short-term intense flash.

The role of magnesium light:

Needless to say, everyone knows that spotlights are used for lighting, so be specific.

A magnesium light is the flash of a camera. The flash used in early photography was made of magnesium powder, so it was called magnesium light. Now it has been replaced by electronic flash. At present, both optical cameras and digital cameras use electronic flash. Both magnesium and xenon can be used in photographic flash. Xenon flashlights can be used thousands of times, while ordinary magnesium lamps can only be used once.
